Some questions according to the free study planner

Dear IMAT learners, I have a question according to the free study planner. I know that I am very late so I don’t expect to get a spot at any of the Universities this year but I want at least start studying and sit the exam this year. Anyways, here is my question:
Do I use the Pearson’s Biology and Cambridge Biology Book at the same time? Or do I use Pearson’s first and Cambridge at the second revision?
Are there any other tipps you could give me for the study planner?
Thanks a lot!

Hello! Focus only on Pearson’s.

Thank you so much! Does your answer apply to chemistry too?

Yes, it’s the same for Chemistry. Best of luck!

Thank you so much for your answer!
